Notes & build logs
Deep dives on the harder things I've built — architecture decisions, low-level details, and what actually shipped.
A Local Trial App for Understanding PCI & Tokenization (Built as an AI Chat Client)
I build banking software for a living, so I wanted a safe place to internalize PCI-style data handling and tokenization without touching real cardholder data. So I built a localized, mock AI chat app as a testbed — a sandbox for secrets isolation, encryption at rest, scope reduction, and a tokenization-shaped trust boundary. This is what I learned.
Building Spider: A Peer-to-Peer Screen Mirroring System from Scratch
A deep dive into building a cross-platform screen mirroring and remote control system — BLE discovery, H.264 streaming, notification forwarding, and a custom binary protocol. No cloud. No SDK. Just raw sockets and system APIs.
Why I'm Starting This Blog
After 7 years of building apps, I'm sharing what I've learned about frontend architecture, React ecosystems, and scaling teams.
